      # We need to run "configure.py" so that pyqtconfig.py is generated, which
      # is needed by QGIS, PyQWT (and many other PyQt interoperable
      # implementations such as the ROS GUI libs). This file is currently needed
      # for generating build files appropriate for the qmake spec that was used
      # to build Qt. The alternatives provided by configure-ng.py is not
      # sufficient to replace pyqtconfig.py yet (see
      # https://github.com/qgis/QGIS/pull/1508). Using configure.py is
      # deprecated and will be removed with SIP v5, so we do the actual compile
      # using the newer configure-ng.py as recommended. In order not to
      # interfere with the build using configure-ng.py, we run configure.py in a
      # temporary directory and only retain the pyqtconfig.py from that.
